BOLT-LOCKING DEVICE.

SPECIFICATION forming part Of Letters Patent No. 403,132, dated May 14, 1889.

Application filed February 16, 1889. Serial No. 300,098- (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES L PENROSE, a citizen of the United States, residing at Chatham, in the county of Columbia and State of New York, have invented certain new and useful Improvements in Bolt- Locking Devices; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to certain new and useful improvements in bolt-locking devices, and more particularly to the means of securing the bolts used in connection with the fishplates in securing or connecting adjacent railway-rails; and it has for its special object to improve upon the device of this character described in an application filed by me upon the 19th day of January, 1889, Serial No. 296,841.

In the device described in said application above mentioned the bolt'is shown as provided with a solid head, and the transverse hole which istapped through the bolt at a point near its opposite end will by this construction be always at a fixed and uniform distance from the bolt-head. I have found this construction objectionable for the reason that the device is only applicable to rails and fish-plates of a uniform thickness.

In the present invention I have overcome this objection by providing in place of the solid head upon the bolt a screw-threaded nut adapted to engage the screw-threaded end of the bolt, the form of the nut being such as to adapt it to fit closely upon the upper face of the base portion of the rail when in position, thus preventing its turning until the cam-lever has been detached and the bolt removed.

To these ends and to such others as the invention may pertain the same consists in the peculiar construction and in the novel combination, arrangement, and adaptation of parts, all as more fully hereinafter described, shown in the accompanying drawings, and then specifically defined in the appended claims.

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part,

of this specification, and in which Figure 1 is a side elevation of the ends of two adjacent railway-rails and fish-plates, the bolts being shown as locked in place in accordance with my invention. Fig. 2 is a transverse section upon line 00 w of Fig. 1. Fig. 3 is a side view of one of the fish-plates removed. Fig. 4 is a perspective view of one of the locking-levers detached.

Like letters of reference refer to like parts throughout the several views.

Reference now being had to the details of the drawings by letter, A designates a railwayrail of ordinary and Well-known construction, and provided with holes for the reception of the bolts used in securing in position the fishplates B and B. The fish-plate which is used upon the inner side of the rail is in all respects similar to the fish-plates ihatare commonly used in connecting the adjacent ends of railway-rails, while the fish-plate B is provided upon its outer face at points adjacent to and immediately above and below the boltholes 6, with recesses or cut-away portions f for the reception of the cam-shaped ends of the locking-lever D, as will be readily understood.

D represents a bifurcated lever, the outer ends of the arms I? of which are cam-shaped and provided with holes 0 for the passage of the bolt (1, which is passed through said hole in the end of the bolt 0, these parts being in all respects identical with the similar parts described in connection with my application filed January 19, 1889.

The bolt 0 is provided at a point near one of its ends with a transverse hole, d, for the passage of the boltwhich is used in attaching the locking-lever D, while the opposite end of the bolt is screw-threaded, as shown at m, for the reception of the nut n, which nut is provided with an enlarged or widened base por tion, 0, and the nut is a size which adapts it when in use to bear directly upon the upper face of the base of the rail.

In operation the nut n is placed upon the screw-threaded end of the bolt 0, and is turned until the said nut has been advanced a sufficient distance upon the bolt to adapt it for use, the distance depending in each particular case upon the thickness of the rail and fish-plates used. After the nut has been properly adjusted the bolt is passed through the hole in the fish-plate and rail, and the lock ing-lever is secured in position and turned back against the face of the rail, so as to lock the parts in place, as will be readily understood. By this construction it will be seen that by properly adjusting the nut upon the bolt the use of Washers may be entirely dispensed with, and a perfect locking of the parts will be at all times assured, and it Willbc also seen that the position of the nut upon the bolt 0, bearing, as it does, directly upon the horizontal portion of the rail-base, precludes the possibility of its being loosened or detached until the locking-lever has been released and the bolt has been removed.

hat I claim as new, and desire to secure by Letters Patent, is-

1. The CO111b'll1&tlO11,Wltl1 the adjacent ends of two connecting railway-rails and the fishplates upon either side thereof, of: a bolt passed through said plates an d rails, a bifurcated lever adapted to embrace the outer end of the bolt, a pin connecting the lever and bolt, and a nut adapted to engage the screw-threaded inner end of the bolt and to bear against the flanged base portion of the rail, substantially as and for the purpose specified.

2. The combination, with the two adjacent railway-rails and the fish plates, of a bolt passed through said rails and plates, a nut engaging the screw-threaded inner end of the bolt, a bifurcated locking-lever the arms of which are cam-shaped and adapted to embrace the end of the bolt, and a pin or bolt passed through said cam-shaped ends of the lever and through a transverse opening through the end of the bolt, substantially as and for the purpose specified.

In testimony whereof I affix my signature in presence of two Witnesses.

CHARLES I. PENROSE.
